servo_v4: Added initial USB PD support for both CHG/DUT ports
- CHG port can connect as SNK at different voltage levels
- DUT port presents as SNK only
- DUT port uses fixed polarity since it has a fixed cable
- Not supporting ALT or ALT_DP modes in terms of svdm messages at
this point.
- No support yet for USB mux.
BUG=chromium:571476
BRANCH=None
TEST=Manual
CHG port: Tested with Zinger and Plankton and 5/12/20V VBUS levels.
DUT port: Tested against Reef and verified that port reached SNK_READY.
